Abstract: PURPOSE: A radiation fin arrangement for condenser of air conditioner is provided to improve heat exchange efficiency of condenser while minimizing the resistance between air current and radiation fin. CONSTITUTION: A radiation fin arrangement is characterized in that the upper portion of a radiation fin(2b) of a condenser(2) is inclined in the direction in which the ascending air current, from among the rotating air current generated by the rotation of the cooling fan, is introduced, while the lower portion of the radiation fin is inclined in the direction in which the descending air current, from among the rotating air current generated by the rotation of the cooling fan, is introduced. Since the air current passing the upper and lower portions of the radiation fin has opposite direction, the upper and lower portion of the radiation fin have opposite angle of gradient. Thus, the volume of air flow among the radiation fins increases while minimizing the resistance between the radiation fin and air current.
